Response of a thin plate structure to high intensity noise was numerically analyzed and compared with experimental results of various stochastic quantities such as correlation, spectrum, probability density function(level counting) and peak counting. The 1st and 2nd modes of panel vibration were taken into account in the analysis. Integration of a pair of two nonlinear equations was performed utilizing the Runge-Kutta-Gill method. A test panel, with dimensions of 326x160x0.8(mm), was riveted on the jig frame and high intensity noise then generated by electro-pneumatic transducers. It was concluded that some stochastic characteristics of calculated strain and displacement agreed with the experiments results, and that the magnitude of the strain and displacement by experiment appeared to be within the range of numerical estimation, when the noise amplitude probabilty density distribution was near normal distribution. We believe this numerical analysis to be useful in estimating outside panel behaviour of aircraft and space vehicle.
